<p>A description is given of the Gmicro/100, a 32-b VLSI microprocessor based on the TRON specification. The Gmicro/100 five-stage pipeline, prejump mechanism, and bitmap manipulation are examined. Performance results are reported. They show that the prejump mechanism, implemented as a hardware solution for the jump problem, executes benchmark programs 16.8% faster on the average. Optimized microinstructions permit bitmap-manipulation instructions to perform two to five times faster than the software loops. The application-specific standard product approach used to implement Gmicro/100 is discussed.</p>
